Title: Decimal arithmetic system
Inventor: YOSHIDA NOBUYUKI
IPC: G06F7/00
Filed: 1980-06-02
Abstract: PURPOSE: To speed arithmetic by simplifying decimal addition by controlling input data in the next arithmetic cycle with stored carries by an arithmetic circuit which has no decimal arithmetic function.  
     CONSTITUTION: Every microinstruction is provided with a decimal arithmetic specifying part and decimal correcting FFs 9 and 10 operate only when decimal arithmetic is specified by the microinstruction; and carries of binary adders 1 and 2  when it is specified are stored to control outputs of registers 5 and 6 during arithmetic in the next cycle. When a carry is issued, its output is made zero and when not,  an arithmetic result is outputted as it is. Therefore, a circuit wherein a decimal  augend and a decimal addend each consisting of an optional number of digits are  simplified adds respective digits in parallel at a relatively high speed.

Filed: 1982-04-30
Abstract: PURPOSE:To prevent an evil effect due to the leakage of a gate signal, by integrating the difference signal between a reference video signal and another video signal for each polarity of the contour signal of said reference video signal and then controlling an image pickup tube by the difference between both integration values. CONSTITUTION:A differential amplifier DFA2 detects the difference between a reference video signal G supplied from a specified image pickup tube PTS and a video signal R supplied from another image pickup tube 1. At the same time, a differential amplifier DFA1 obtains the difference between the signal G and a signal G2 obtained by delaying the signal G to obtain a contour signal. Then gate circuits GA1 and GA2 are conducted by the polarity of the contour signal, and the output of the amplifier DFA2 is integrated by integrators I1 and I2 for each polarity of the contour signal. The output difference between both integrators I1 and I2 is obtained by a differential amplifier DFA3 to obtain an error signal. A displacement signal for picture position which is applied to a deflection circuit of the tube 1 is produced by the above-mentioned error signal.

Filed: 1987-03-26
Abstract: PURPOSE:To reduce the area of a first substrate using an expensive ceramic by disposing on the same support base the first substrate with a plurality of light-emitting diode chips mounted thereon and a second substrate with a plurality of driving elements mounted thereon. CONSTITUTION:A substrates 6a for mounting light-emitting diode chips 1 thereon is required to have a flat surface, be free of warp and have high thermal conductivity, and is therefore constituted of a ceramic substrate. On the other hand, substrates 6b for mounting driving elements 2 thereon are not several required to have the above-mentioned conditions, and may therefore be glass-epoxy resin substrates or the like. Both of the substrates 6a and 6b are disposed on a metallic support base 4 having a favorable heat-releasing effect. The driving elements 2, the diode chips 1 and the substrates 6b are connected to each other by gold or aluminum wires 5 by a wire bonding method. Thus, the area of an expensive ceramic substrate can be reduced. When one of the light-emitting diode chips has a defect, it is sufficient in the worst case to discard only the substrate corresponding to the defective chip, so that the yield of the product is enhanced.
